Application filed February 27, 1913 Serial No. 750,997.

To all whom it may concern:

Be it known that I, GEORGE A. MELLON, a citizen of the United States ofAmerica, and a resident of the city of St. Louis and State of Missouri,have invented certain new and useful Improvements in Spring Bed-Bottoms, of which the following is a full, clear, and exact description,reference being had to the accompanying drawings, forming a part of thisspecification.

My invention relates to bed bottoms of the kind in which upright coilsprings are utilized, and the invention has several objects, which maybe set forth as follows: To produce a spring bed bottom of aconstructionin which the top of the spring bed bottom is divided into twolongitudinal sections, in either of which the springs may yieldindependently of the other section, in: order that when the sectionsarein service to support persons of unequal weight, a greater depression ordisplacement of the springs of one section will not be transmitted tothe springs of the other section. In my improvement, this object isattained by dividing the bed bottom at its surface in i such manner thatthe springs of each of the sections are free of connection at theirupper ends with the springs of the other sect-ion,

and all of them in the two sections are? joined by suitable connectingmeans to end rails of the bed bottom frame common to both of thesections. Figure I is a top or plan view of myv spring bed bottom, thetransverse slats and bottom stay wires being omitted to avoid confusionin the illustration. a side elevation 6f the bed bottom. Fig. III is aperspective view of a portion of the Fig. II is bed bottom frame. Fig.IV is an enlarged top or plan view of fragments of the top coils of twoof the upright springs in .a transverse row of said springs, and thehinge connection uniting said coils. Fig. V is an enlarged crosssection, taken on line VV, Fig. IV.

In the drawings: 1 designates the end rails of the frame of my bedbottom, which extend the entire width of said bed bottom. These endrails serve as supports for ml rails. The spring supportin upright coilspring supporting 'members, comprising drop hangers 2, longitudinalrails3, securedto sai drop hangeraand transverse slats 4, attached tosaid longitudiframe members mentioned, inclusive of t e drop:

hangers 2, are supported by the end rails 1, which serve to support thecoil spring sections of my bed bottom.

The upright coil springs of my bed bottom are all similar inconstruction, and they are arranged in rows extending bothlongitudinally and transversely of the bed bot tom, above and resting onthe spring supporting frame suspended'from the end rails 1. Inasmuch,however, as the coil spring structure is divided above its base intosections, I will, for the sake of clearness of description, designatethe upright coil springs in one section A and the coil springs in theother section at. These springs are all connected at their lower ends bycrossing wires, as is usual in coil sprin bed bottom structures, thesewires an the springs beingsupported by the longitudinal bars 3 and slats4 of the bed bottom frame.

The upright coil springs A and a are connected to each other in both thelongitudinal and transverse rows of such springsv by longitudinal tiewires B, which are applied to the top coils of said springs in a mannerto be hereinafter explained; and the ends of these tie wires areconnected to the end rails 1 of the bed bottom frame by helicaltensionsprings G, with an object in view that will be hereinafter made clear..

By referring to Fig. I, it will be observed that the upright coilsprings A and a, in

no connection with each other, except through the end rails of the bedbottom frame. The outer longitudinal rows of the upright coilsprings Aand a areattached to border strips or'bars H, by 'any suitable means,such as wire loops fit coils of the springs, and united at their en tothe end rails 1 by. helical tension springs G.

From the foregoing, it will be quite apparent that the spring sectionsof my bed bottom, comprising the upright coil sprin s A and a, areentirely independent of eac other above the bases ofsaid springs; and,

ted to the to i a;

springs in one section being communicated to the springs in the othersection. Therefore, when my bed bottom is in service to support twopersons of unequalweight lying above the two sections of the bed bottom,the

springs will yield in each section coinmensurate only to the weightimposed thereon, without the objectionable uneven depression of springstructure that occurs in the ordinary continuous spring structures ofbed bottoms when they are required to support persons of unequal weight.

I will next proceed with the description of the hinge sections for thetop coils of the upright coil springs of my bed bottom,

which are, as previously stated, included in the longitudinal tie wires,and serve to'join the upright springs, both longitudinally andtransversely of the bed bottom. These connections are integral parts ofthe longitudinal tie wires, and each connection comprises kinks C,formed to extend laterally from spaced portions in the tie wirecontaining the connection, and in which the top coil of one of anadjoining pair of upright coil springs is fitted. As illustrated in thedrawings, these kinks extend beneath the coil they are fitted to, andthen upwardly and over the coil. The remainder of the connection is inthe form of a loop comprising transverse members D, which extendlaterally from the kinks C, return bends E, which receive the top coilof the second upright spring, and a U-shaped portion F, which extendsbackwardly from the return 4 0 bends E, beneath the top coils of the twosprings, toy and preferably beyond the top coil that is fitted in thekink C of the connection. It will be obvious that a connection made asdescribed joins the top coils of springs in a; transverse row of my bedbottom in such manner as to permanently connect them; and, at the sametime, permit freedom of vertical movement of each spring relative to theother. It will also be obvious that a series of such connections unitingthe springs in the transverse rows and also extending along thelongitudinal rows of springs serve to join the springs in the oeaeae llongitudinal rows in a manner that will permit of their movementlongitudinally of the bed bottom when they are subjected to pressure.The upright springs may, therefore, be depressed or moved laterally,either transversely or longitudinally of the bed bottom, according topressure imposed against them, either uniformly or ununiformly; and,inasmuch as the tie wires in which the connections are included areunited to the end rails of the bed bottom frame by the tension springsG, the upright coil springs will always be returned to their normalpositions when pressure against them is relieved.

I claim: p

1. In a bed bottom, aframe comprising a bottom structure, and a. pair ofend rails above said bottom structure, and two-separate spring. sectionssupported by said bottom structure; said spring sections being securedindependently of each other to the same end rails. i

2. In a bedbottom. a frame comprising abottom structure and a pair ofend rails above said bottom structure, two sets of spring sectionscomprising upright coil springs resting on said bottom structure, tiewires 'connecting the upper ends of said upright coil springs, the tiewires in each spring section being independent of the tie wires on theother spring section andbeing connected to the same end rails.

2:). In a bed bottom, a frame comprising a pair of end rails at the topof said frame. and two separate spring sections supported by said frame,the spring sections comprising springs and means at their lowerendsconnecting the springs of one section with those of the other section,and means connecting the upper ends of the springs in both sections tothe "same end rails.

4. In a bed bottom. a frame comprising a pair of end rails and twoseparate spring scctions supported by said frame. each of said springsections comprising upright coil springs. tie wires connecting saidupright springs, and tension springs joining said tie wires to said endrails.
